Hi, I'm trying to add the dpdk ports to the ovs bridge, and while doing so, i see the ovs daemon crashing with the 'operation not permitted' error, here's my architecture, i am on a debian vm (pseudo host) that has virt-io devices attached to it, i'm binding these virt-io's to the dpdk (igb_uio) and trying to add it to the ovs bridge. dpdk version: 17.11.2 ovs-version: 2.9.0 i did try looking for cores in /var/lib/systemd/coredump, but there are no cores there, strange. And i cannot look for cores in the current directory of that process because it keeps getting killed (as the daemon tries to come up and crashes and keeps at it forever)

I'm not sure where i'm going wrong. Any advise is appreciated.
